ABSTRACT

A low or zero calorie sweetener composition with sweetness synergy, providing a reduction in off-taste and a desirable temporal profile. The sweetener composition is suitable for use as a substitute for high calorie sugars. The sweetener composition is for use in food and beverage products, pharmaceutical products, nutritional product and cosmetic products.

FIELD OF THE INVENTION

The present invention relates generally to a low or “zero”-calorie synergistic sweetener composition. In particular, the present invention relates to a sweetener composition with sweetness synergy, a reduction of off-taste and a desirable temporal profile. The present invention also relates to food or beverage products comprising said sweetener composition.

BACKGROUND OF THE INVENTION

Many food and beverage products contain nutritive sweeteners such as sucrose (generally referred to as ‘sugar’ or ‘table sugar’), glucose, fructose, corn syrup, high fructose corn syrup and the like. Such sweeteners supply not only sweetness to the food and beverage products, but also bulk, texture and desirable functional properties such as browning, humectancy, freezing point depression and the like. They also produce a favorable sensory response, for example in terms of quality of sweetness, lack of bitterness and off taste, desirable temporal profile and desirable mouthfeel.

Although desirable in terms of taste and functional properties, excess intake of nutritive sweeteners, such as sucrose, has long been associated with an increase in diet-related health issues, such as obesity, heart disease, metabolic disorders and dental problems. This worrying trend has caused consumers to become increasingly aware of the importance of adopting a healthier lifestyle and reducing the level of nutritive sweeteners in their diet.

In recent years, there has been a movement towards the development of replacements for nutritive sweeteners, with a particular focus on the development of low or zero-calorie sweeteners. An ideal replacement for a nutritive sweetener is a sweetener that has the same desirable taste characteristics and functional properties as the nutritive sweetener, but which also has fewer or substantially no calories. Aiming to meet this growing need, the market has been flooded with possible candidates to replace conventional nutritive sweeteners. Unfortunately, however, many of the low or zero calorie replacements offered on the market lack one or all of the necessary characteristics, and often exhibit bitterness or off-taste. Therefore, many of the proposed sweeteners are not an ideal replacement for nutritive sweeteners.

One proposed alternative to nutritive sweeteners is allulose (also known as D-psicose). Allulose is known as a “rare sugar”, since it occurs in nature in only very small amounts. It provides around 70% of the sweetness of sucrose, but only around 5% of the calories (approximately 0.2 kcal/g). It may therefore essentially be considered to be a ‘zero calorie’ sweetener.

In view of its scarcity in nature, production of allulose relies on the epimerization of readily available fructose. Ketose-3-epimerases can interconvert fructose and allulose, and various ketose-3-epimerases are known for carrying out this conversion.

U.S. Pat. No. 8,030,035 and PCT publication no. WO2011/040708 disclose that D-psicose can be produced by reacting D-fructose with a protein derived from Agrobacterium tumefaciens, and having psicose 3-epimerase activity.

US patent publication no. 2011/0275138 discloses a ketose 3-epimerase derived from a microorganism of the Rhizobium genus. This protein shows a high specificity to D- or L-ketopentose and D- or L-ketohexose, and especially to D-fructose and D-psicose. This document also discloses a process for producing ketoses by using the protein.

Korean patent no. 100832339 discloses a Sinorhizobium YB-58 strain which is capable of converting fructose into psicose (i.e. allulose), and a method of producing psicose using a fungus body of the Sinorhizobium YB-58 strain.

Korean patent application no. 1020090098938 discloses a method of producing psicose using E. coli wherein the E. coli expresses a polynucleotide encoding a psicose 3-epimerase.

Allulose is present in processed cane and beet molasses, steam treated coffee, wheat plant products and high fructose corn syrup. D-allulose is the C-3 epimer of D-fructose and the structural differences between allulose and fructose result in allulose not being metabolized by the human body to any significant extent, and thus having “zero” calories. Thus, allulose is thought to be a promising candidate as a replacement for nutritive sweeteners and as a sweet bulking agent, as it has no calories and is reported to be sweet while maintaining similar properties to sucrose.

One of the most recently proposed alternatives to table sugar is Monk Fruit extract. Monk fruit is a fruit from the plant species Siraitia grosvenorii, of the Cucurbitaceae family, and is a type of small melon which grows exclusively in tropical and subtropical regions of Southeast Asia. This fruit is also known as “Luo han guo”, is roughly 200 times sweeter than cane sugar, and provides calorie-free sweetness. The main sweet components of Monk Fruit leading to its sweet taste are known as mogrosides. Mogrosides are members of the family of triterpene glycosides. The sweet taste of mogrosides is thought to be related to the number of glucose units present in the mogroside. Examples of mogrosides found in Monk Fruit are Mogroside V, Mogroside IV, Mogroside VI, Oxomogroside V, Mogroside IIIE and Siamenoside I.

However, more recent studies have shown that some mogrosides may exhibit an off-taste and a less desirable temporal profile. Furthermore, allulose may have limitations in use due to cost and digestive tolerance in some applications. Therefore, there is a need to provide an improved replacement for sucrose and other nutritive sweeteners that has low or zero-calories and is without limitations in use, but which also has taste characteristics similar to those of sucrose.

The present invention seeks to provide a solution to the above mentioned problem by providing a sweetener composition having taste characteristics comparable to sucrose but having low or no calories. Advantageously, the present invention also seeks to provide a sweetener composition which provides a reduction in off-taste or off-flavor, a desirable temporal profile and improved mouth feel, compared with known proposed sweeteners.

DETAILED DESCRIPTION

The present invention is based on the finding that allulose and at least one mogroside, when present in a composition, exhibit sweetness synergy whereby the blend is sweeter than the expected sweetness based on the sweetness of its components. Furthermore, it has been found that this blend of allulose and at least one mogroside addresses problems associated with the individual components, in particular, with regard to the off-flavor and/or undesirable temporal profile that may be associated with some mogrosides.

Due to the presence of the zero calorie sweeteners, the sweetener composition is low or “zero” calorie. Furthermore, as a consequence of the sweetness synergy exhibited by the composition, the amount of the composition required to provide a given level of sweetness is less than would be expected in the absence of synergy, thereby allowing a further reduction in calories. Thus, the sweetener of the present invention provides enhanced sweetness, improves the balance of flavor by reducing off-taste or off-flavor, and provides a more desirable temporal profile, while at the same time allowing a significant reduction in calories compared to a sweet-equivalent amount of a conventional nutritive sweetener.

Using the sweetener composition of the present invention allows delivery of an increased sweetness in food or beverage products when compared to the individual components used separately. This enhanced sweetness means that a smaller amount of sweetener can be used in these products, to provide a temporal and taste profile that closely matches that of sucrose.

In general terms, the present invention relates to a sweetener composition comprising allulose and at least one mogroside.

EXAMPLES Example 1 Evaluation of the Sensory Properties of the Sweetener Composition of the Invention

Materials and Methods

Round table evaluations were performed with a number of test panelists. Equal sweet 10 SEV concentrations in neutral pH water were made for allulose and PureFruit™ Select and as well as equal (50/50) mixture of allulose and PureFruit™ Select. PureFruit™ Select is commercially available from Tate & Lyle. All mixtures were calculated using the Beidler mixture equation for the sweeteners. The Beidler mixture equation for sweeteners is as follows:

${SEV} = \frac{{conc} \cdot R_{\max}}{{conc} + {1/K}}$

The concentration of each component in the mixture in ppm is divided by SEV (c/R) and is plotted against concentration, c. The slope of the linear regression is the maximum SEV (R_(max)). The y-intercept of the linear regression multiplied by R_(max) is the half-maximal sweetness concentration, 1/K. R_(max) and 1/K are the two parameters used in the Beidler equation.

The equal-molar mixtures were tested against reference samples for the panelists to determine SEV values. Reference mixtures were 4%, 6%, 8%, 10%, 12%, and 14% sucrose in neutral pH water.

The solutions were served in 2 ounce (approximately 60 ml) soufflé cups coded with 3-digit codes at room temperature. A two minute wait period between samples was enforced. RO water and unsalted crackers were available for the panelists to clear their palates before and during testing. EyeQuestion was used for ballot development and recording of results.

Results were collected in EyeQuestion for calculating approximate SEV level of each test sample. Z-test statistics with a=0.07 was used to determine significant difference from the 50/50 SEV mixture predicted value.

Results

FIG. 1 illustrates the SEV yielded for the sweetener composition of the invention. This value was compared with the predicted SEV for each of the individual component parts (as illustrated by the straight shaded line on each graph). Surprisingly, the composition of the invention, comprising allulose and PureFruit™ Select exhibited sweetness synergy. The composition yielded an SEV of 9.85, which was a higher SEV via p-value for z-test above predicted 50/50 SEV values for the blend at a greater than 90% confidence interval.

CONCLUSION

The sweetener composition of the present invention exhibits a statistically significant sweetness synergy.

Example 2 Determination of the Temporal Profile of the Sweetness Composition of the Invention

As the composition of the invention exhibited statistically significant sweetness synergy, the temporal profile of this composition was also determined. This experiment was undertaken to determine if allulose had any influence on the temporal profile of PureFruit™ Select when both components are present as a blend in a sweetener composition.

Materials and Methods

Temporal profile was completed with a trained descriptive panel. Panelists had several orientation rounds of the test samples to familiarize themselves with the protocol and the test samples. The tests were conducted as complete block designs in 3 replicates with the trained panel and were done over two testing days (one for each formula set). The presentation order was rotated. The solutions were served in 2 ounce (56 g) soufflé cups labeled with 3-digit codes, and panelists received 20 ml of each sample and were instructed to use the entire sample. Panelists were instructed to sample the product by placing the sample in their mouths and swallowing or spitting out the sample immediately while starting their intensity rating for sweetness at the same time using EyeQuestion. Intensity ratings for sweetness were collected for 2 minutes. Panelists had a two minute wait time between samples and at least a 10 minute break in-between repetitions. Panelists cleaned their palates with bottled water and unsalted crackers.

The maximum intensity of each panelist for each sample was determined for the entire temporal profile, and the overall temporal profile data for that sample was then calculated using normalization as % of maximum (e.g. maximum value is 100%, and all intensity values are rated as a % based on value divided by maximum intensity value). Once normalized data was calculated for each panelist, averaged response across panelists was calculated. Based on these normalized values, the averaged normalized % temporal profile was then calculated as using normalization as % of maximum (e.g. max value is 100%, all intensity values are rated as a % based on value divided by maximum intensity value), and plotted for each sample.

Results

The sweetness temporal profile reported for the composition of the invention is shown in FIGS. 2 and 3. FIG. 2 illustrates sweetness onset and reports the normalized maximum intensity for each sample over a time period 0 to 140 seconds. FIG. 3 illustrates sweetness linger and reports the normalized maximum intensity for each sample over a time period 0 to 20 seconds.

As illustrated in FIGS. 2 and 3, the composition of the invention improves the temporal profile relative to PureFruit Select™ alone. As illustrated in FIG. 2, the temporal onset is quicker and as illustrated in FIG. 3 the temporal linger is shorter, in the composition comprising allulose and PureFruit Select™ mixture. The temporal profile is similar to that of allulose alone and sucrose. The temporal profile of sucrose is illustrated in FIGS. 4 and 5.

CONCLUSION

Mixing PureFruit™ Select with allulose improves the temporal profile onset and linger properties of PureFruit™ Select.

Example 3 Table-Top Sweeteners

Three combinations of allulose and monk fruit extract (Luo Han Guo) were prepared. One combination included only allulose and monk fruit extract (PureFruit™ Select); one combination additionally included a stevia extract (Tasteva™) and Rebaudioside A (Reb A); and one combination additionally included sucrose:

Total dry weight of each table-top sample Sample Table top composition in 200 mL of coffee 1 98.7% Allulose + 1.3% 3.53 gram  PureFruit ™ Select 2 97.24% Allulose + 1% Tasteva ™ + 1.66 gram  1.11% PureFruit ™ Select + 0.65% Reb A 3 72.28% Allulose + 1.72% PureFruit ™ 2.4 gram Select + 26% sucrose Truvia ™ (comparative) 3.5 gram Sucrose (control) 8.4 gram

Each combination was dissolved in hot coffee. The total weight of each combination was designed such that the sweetness of each combination in 200 ml of coffee is similar to that of 8-10 grams of sucrose in the same amount of coffee. The coffee was made by brewing 91.9 grams of Starbucks™ Blounde Veranda Blend ground coffee with about 1600 mL of water. The calorie content of each combination was targeted to be less than 5 kcal/200 mL coffee. Five panelists were asked to compare the sweetness and taste profile of each combination against sucrose control and Truvia™ (a commercially available stevia-based sweetener) in hot coffee on a scale of 1 to 5:

Sample 1 Sample 2 Sample 3 Truvia ™ Average rating 2.4 2.2 2.2 1.2

It was unexpectedly found that allulose can make low calorie table-top sweetener taste more like sugar (sucrose). It is also unexpectedly found that allulose-based low or zero calorie table top sweetener taste significantly better than an erythritol-based table top product.
